Politics

The term lifestyle in politics can often be used in conveying the idea that society be accepting of a variety of different ways of life—from the perspective that differences among ways of living are superficial, rather than existential. Lifestyle is also sometimes used pejoratively, to mark out some ways of living as elective or voluntary as opposed to others that are considered mainstream, unremarkable, or normative.
Within anarchism, lifestylism is the view that an anarchist society can be formed by changing one's own personal activities rather than by engaging in class struggle.

Advertising and marketing

In business, "lifestyles" provide a means by which advertisers and marketers endeavor to target and match consumer aspirations with products, or to create aspirations relevant to new products. Therefore marketers take the patterns of belief and action characteristic of lifestyles and direct them toward expenditure and consumption. These patterns reflect the demographic factors (the habits, attitudes, tastes, moral standards, economic levels and so on) that define a group. As a construct that directs people to interact with their worlds as consumers, lifestyles are subject to change by the demands of marketing and technological innovation.
